RATION.

OF ST. LOUIS, MISSOURI, .A CORPO- BRAKE-BEAMSFULCRUM.

SPECIFICATION forming part Of Letters Patent N0. 7 08,352, dated September 2, 1902.

Application filed January 11, 1902. Serial No. 89,286. (No model.)

To all whom it may concern:

Be it known that I, PHILIP T. HANDIGES, a citizen of the United States, residing in the city of St. Louis, in'the State of Missouri, have invented certain new and usefulImprovements in Brake Beam Fulcrums, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification.

My invention relates to that class of fulcrums used upon brake-beams to receive the brake-lever applied thereto.

The object of my invention is to produce a fulcrum of the character named in which the fulcrum-jaw is removably held between a pair of mating socket clamp members, by which construction I am enabled to make use of a brake-lever-receiving jaw composed of a forging that will withstand greater strain and is of superior wearing quality to such jaws as now used.

My invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a side view of my improved fulcrum shown applied to a brake-beam that appears in cross-section. Fig. II is a top or plan View of the fulcrum. Fig. III is a front view. Fig. IV is a detail perspective View of the two mating socket clamp members of the fulcrum. Fig. V is a top view of the fulcrumjaw. Fig. VI is a longitudinal sectional view taken through the fulcrum-jaw on line VI VI, Fig. V.

1 designates a brake-beam, that may be of the I form shown or of any desirable construction, having flanges 2.

3 designates the fulcrum-jaw of bifurcated form and provided with a pin-hole 4, through which the pin or bolt of the brake lever passes. In the top and bottom faces of the fulcrum-j aw are recesses 5, that are positioned near the rear end of the jaw. (See Figs. V and VI.)

6 designates socket clamp members, by which the jaw 3 is held. These socket clamp members are approximately alike in construction and are complementary to each other, so as to mate when assembled. Each member 6 has arear arm 7, adapted to lie against the web of the brake-beam 1, as seen in Fig. I, and contains an aperture 8, through which the rivet or bolt 9 passes to secure the members to the brake-beam.

Projecting at approximately a right angle from the arm 7 of each clamp member 6 is a rear body-wall 10, that is adapted to fit against the inner face of the brake-beam fiange 2 at the side of the brake-beam occupied by the member. At the termination of each bodywall 10 the body of the member extends forwardly at 11 and unites with a forward bodywall 12, between which and the rear bodywall is a groove 13, as seen in Fig. IV.

At the side of each socket clamp member containing the groove 13 is a strengtheningweb 14, that projects outwardly and downwardly from the front and rear body-walls to resist strain produced upon the members at the point mentioned. At the opposite side of each socket clamp member from that just described is an angular tongue 15, that constitutes the front wall of the socket member and occupies a position parallel to the rear "body-wall 1O.

16 designates wings extending forwardly and obliquely from the bodies of the socket clamp members 6, and extending inwardly at the ends of said wings are flanges 17, each provided with tongues 18, adapted to meet over the jaw 3 when it is seated between the wings 16, thereby forming with said wings a clamping-inclosure for the jaw. The flanges 17 are each cut away, as shown at 19, to produce a notch therein, as seen in Figs. I, II, and III, in which the brake-lever mounted in the fulcrum-jaw may operate.

20 designates bosses projecting from the inside faces of the wings 16 and adapted to seat in the. recesses 5, contained by the fulcrum-jaw, to provide for the firm retention of said jaw between the socket clamp members, by which it is held.

By the construction of fulcrum herein described the jaw 3 is firmly held within the socket clamp members 6, which are interlockingly engaged over the jaw, so that separation thereof is prevented while the fulcrum is in use, thereby avoiding all possibility of Vertical strain causing the disengagement of the jaw from the clamp members.

I claim as my invention- 7 1. As a new article of manufacture,a brakebeam fulcrum comprising a pair of socket clamp members, and a jaw seated and held within said members, substantially as described.

2. The combination with a brake-beam, of a jaw and a pair of socket clamp members interlockingly engaged and adapted to hold said jaw between them, substantially as described.

3. A brake-beam fulcrum comprising a pair of socket clamp members grooved to fit over the flanges of a brake-beam, and having forwardly-extending wings; and a jaw seated and held between said wings, substantially as described.

4. A brake-beam fulcrum comprising a pair of socket clamp members grooved to fit the flanges of abrake-beam,and having forwardlyprojecting wings, mating flanges carried by said wings adapted to abut against each other, and a jaw seated and held between said wings, substantially as described.

5. A brake-beam fulcrum comprisinga pair of socket clamp members having a body portion adapted to fit the brake-beam, wings proj ecting from said body, bosses carried by said wings, and a jaw positioned between said wings and having recesses adapted to receive said bosses, substantially as described.

6. A brake-beam fulcrum comprising a pair of socket clamp members having a grooved body portion adapted to fit the flanges of the brake-beam, wings projecting obliquely from said body portion, flanges projecting from each of said wings having tongues adapted to abut against the tongues of the mating socket clamp members, bosses located on the inside faces of said wings, and a jaw seated between said wings having recesses adapted to receive said bosses, substantially as described.

In testimony whereof I have hereunto set my hand this 8th day of January, 1902.

PHILIP T. HANDIGES.
